Pondok Pesantren Darul Muttaqin, located in Batu City, East Java, is an Islamic boarding school with a mission to provide non-profit education services. The current number of students is 63, with predictions for an increase in the coming years. This growth in student numbers will impact the increasing demand for drinking water that the boarding school must supply. The current situation shows that the drinking water supply capacity is insufficient for the number of students and staff. Additionally, relying on gallon water providers incurs high costs, traditional methods require significant energy and time, and the quality of the water produced is still inadequate, posing a health risk. Based on an analysis of the partner’s situation and conditions, this community service initiative aims to provide training through technology transfer on drinking water treatment to the students and staff of Pondok Pesantren Darul Muttaqin. The community service activities include delivering materials on drinking water quality, introducing the reverse osmosis system for water treatment, practical sessions on using reverse osmosis equipment, and monitoring. The success of this initiative is measured through partner satisfaction surveys, where 43% of respondents agreed, and 15% strongly agreed with the benefits of the activity. Abstrak Pondok Pesantren Darul Muttaqin yang terletak di Kota Batu, Jawa Timur merupakan pesantren yang memiliki misi memberikan layanan pendidikan non-profit. Santri Pondok Pesantren Darul Muttaqin berjumlah 63 santri, yang mana jumlah ini diprediksi akan bertambah pada tahun-tahun berikutnya. Penambahan jumlah santri ini akan berdampak pada meningkatnya jumlah air minum yang harus disediakan oleh pihak pondok pesantren. Kondisi yang terjadi yaitu kapasitas penyediaan air minum tidak sebanding dengan jumlah santri dan staf pondok pesantren, biaya yang tinggi jika ingin menggunakan jasa penyedia air galon, banyaknya tenaga dan waktu yang dibutuhkan jika menggunakan metode tradisional serta kualitas air yang dihasilkan masih belum baik sehingga beresiko menimbulkan penyakit. Berdasarkan analisis situasi dan kondisi mitra, maka pengabdian ini bertujuan untuk memberikan pelatihan melalui transfer teknologi tentang pengenalan pengolahan air minum kepada santri dan staf Pondok Pesantren Darul Muttaqin. Pelaksanaan pengabdian meliputi pemberian materi tentang kualitas air minum, proses pengolahan air minum dengan sistem reverse osmosis, praktik langsung penggunaan alat reverse osmosis dan monitoring. Ketercapaian pelaksanaan pengabdian ini dilihat dari kepuasan mitra melalui kuesioner yaitu rata-rata tingkat kepuasan mitra menunjukkan bahwa 43% menjawab setuju dan 15% menjawab sangat setuju terhadap kebermanfaatan kegiatan ini.

The greenhouse effect, which is a global issue, can provide benefits in the agricultural sector, especially in the processing of essential oils, which require drying raw materials before being purified. This is necessary to increase process efficiency, one of which is processing kaffir lime leaves. Drying is generally done in a simple way, but it has problems such as high-water content (approximately 15%), unstable weather, and slow drying speeds that cause leaf damage and fungus affecting essential oil quality. The solution is to utilize suitable technology, such as a greenhouse system. The study compares greenhouse drying methods with forced airflow and open sun drying, focusing on moisture content. The moisture content was measured using a moisture balance at each drying time. The result is that Greenhouse Force Circulation (GFC) drying effectively decreases kaffir lime leaves' moisture compared to Open Sun Drying (OSD), as evidenced by its higher drying rate.

Stevia leaf extract (Stevia rebaudiana Bertoni) could have been utilized as an alternative natural sweetener because it possessed a sweetness level 300 times that of sucrose sugar. However, stevia leaf extract still contained a bitter taste attributed to the presence of tannins. The method that can be used to reduce tannin content is batch adsorption using activated carbon. This study aimed to investigate the batch adsorption process for the tannin content of stevia leaf extract using activated carbon with variable adsorption times ranging from 5 to 180 minutes, which included the appropriate adsorption isotherm model and adsorption energy. Stevia leaves were extracted through maceration with 70% ethanol. The results of the stevia leaf extract were adsorbed in batches using activated carbon treated with 1M NaOH. The analysis was carried out by testing the tannin content (mg/g TAE) using a UV-Vis spectrophotometer at a wavelength of 735 nm and calculating the adsorption isotherm and adsorption energy. The results showed that the tannin content before adsorption was 0.910 mg/g TAE, and the lowest tannin content was 0.040 mg/g TAE at 100 minutes. The tannin content decreased between 590 minutes, remained constant, reached equilibrium at 95120 minutes, and increased again at 125180 minutes. The suitable adsorption isotherm model was the Freundlich isotherm with a value of R2 = 0.9998; KF = 25.293 [(mg/g)(L/mg)1/nf], and adsorption energy = -8.03 kJ/mol. The adsorption that occurred was classified as physical adsorption.

Kegiatan pondok pesantren tidak lepas dari penggunaan produk sanitasi untuk menjaga kesehatan dan kebersihan. Salah satu produk sanitasi yaitu hand sanitizer. Tujuan dari kegiatan pengabdian ini yaitu melatih analisis kelayakan ekonomi produk sanitasi dalam upaya self-sufficiency di pondok pesantren Bahrul Maghfiroh Malang. Melalui pengabdian ini diharapkan kesehatan dan kebersihan santri terjaga dan dapat menciptakan pondok mandiri secara finansial. Pengabdian ini dilakukan daring dengan memberikan pelatihan formulasi hand sanitizer dan analisis kelayakan ekonomi meliputi perhitungan harga jual produk dan kriteria investasi. Berdasarkan simulasi hasil perhitungan, didapatkan harga jual hand sanitizer kemasan 100 ml yaitu Rp 11.528,00 dengan laba 5% dari harga pokok penjualan. Dengan interest rate (IR) sebesar 4,25%, didapatkan nilai NPV sebesar Rp 235.841.940,31 dan IRR sebesar 58,82%, dimana investasi produk sanitasi ini dikategorikan visible (layak) karena NPV > 0 dan IRR > IR. ROI yang didapatkan sebesar 94,89% dengan PBP selama 1,05 tahun. Capaian pelaksanaan kegiatan pengabdian ini dapat dilihat dari kepuasan mitra dengan hasil kuesioner rata-rata kepuasan sekitar 74% responden menjawab setuju terhadap kebermanfaatan kegiatan ini. Oleh karena itu, kegiatan analisis kelayakan ekonomi produk sanitasi perlu dilakukan secara kontinyu dan bisa dikembangkan untuk produk sanitasi yang lain.
